4.Apply a QoS profile to a port(s).
4.8.2 QoS Control List Configuration
This page lists the QCEs for a given QCL.
Frames can be classified by 4 different QoS classes: Low, Normal, Medium, and High.
The classification is controlled by a QoS assigned to each port.
A QCL consists of an ordered list of up to 12 QCEs.
Each QCE can be used to classify certain frames to a specific QoS class.
This classification can be based on parameters such as VLAN ID, UDP/TCP port, IPv4/IPv6 DSCP or Tag Priority. Frames not matching any of the QCEs are classified to the default QoS Class for the port.

• | QCE Type | Specifies which frame field the QCE processes to determine the QoS class of the |
|
| frame.The following QCE types are supported: |
• Ethernet Type: The Ethernet Type field. If frame is tagged, this is the Ethernet Type that follows the tag header.
• VLAN ID: VLAN ID. Only applicable if the frame is VLAN tagged.
• TCP/UDP Port: IPv4 TCP/UDP source/destination port.
• DSCP: IPv4 and IPv6 DSCP.
• ToS: The 3 precedence bit in the ToS byte of the IPv4/IPv6 header (also known as DS field).
• Tag Priority: User Priority. Only applicable if the frame is VLAN tagged or priority tagged.
